QS Sea Water Pump
1. QS Sea Water Pump Introduction
Sea water pump is one type of pumping machine for sea watertransfer.it is always called sea water pump or short as SW pump. The QS series is single double-suction, horizontal split casing centrifugal pumps, pumps generating high heads have doublevolutes to reduce radial forces. Replaceable wear ring protect the casing atthe impeller running clearances. Vertical or horizontal, soft packing ormechanical seal, grease or oil lubrication bearing on request. It is alsoelectric motor or diesel engine driven on request.
2. QS Sea WaterPump Feature
(1)Have QS and QSH two types. Viewedfrom motor, the direction of the QSH pump is anti-clockwise, that is thesuction in the left, the discharge in the right. The rotating direction of thetype QS pump is clockwise, that is the suction in the right, the discharge inthe left. Also can move the driver to another edge according to the user’srequires. Then, the rotating direction, the suction and discharge direction isin the opposite as the described above.
(2)Supply full set split-casing centrifugal pump, motor, coupling, the inletdiameter less than 200mm match the common base.
(3)The pump is axial split casing construction.
(4)Large capacity
